How do you do (x squared -2) (x squared 3x 5)?
(x^2-2) (x^2+3x+5)= x^2(x^2+3x+5) -2(x^2+3x+5)= x^4 +3x^3 +5x^2 -2x^2 -6x -10= x^4 +3x^3 +3x^2 -6x -10
What is equivalent to 4(5 x)?
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
What is equivalent to 2 5?
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
How do you solve 5x-5 equals 3x-9?
5x - 5 = 3x - 9 add 5 to both sides: 5x =3x -4 subtract 3x from both sides: 2x = -4 Divide both sides by 2: x = -2
What is the solution to the equations y equals 3x plus 4 and y equals 2 -7x showing key stages of work?
If: y = 3x+4 and y = 2-7x Then: 3x+4 = 2-7x So: 3x+7x = 2-4 => 10x = -2 => x = -1/5 By substitution: y = 17/5 Solution: x = -1/5 and y = 17/5

What expression is equivalent to 2(3x 4)-3(x-5)?
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
Generating equivalent expression 3x-9 plus 3x plus 5?
The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
What is equivalent to 4(5 x)?
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
What is equivalent to 2 5?
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
What is x plus 4z-5-3x then x equals 2 and z equals 3x?
If the question is x + 4z - 5 - 3x when x = 2 and z = 3x, then First simplify the original statement x + 4z - 5 - 3x = 4z - 5 - 2x Secondly substitute in 3x for z 4z - 5 - 2x = 4*3x - 5 - 2x = 12x - 5 - 2x = 10x - 5 Lastly substitute 2 for the x 10x - 5 = 10*2 - 5 = 20 - 5 = 15 or x + 4z - 5 - 3x when x = 2 and z = 3x, so z = 3*2 = 6 x + 4z - 5 - 3x = 4z - 5 - 2x (replace the variables with the corresponding values) = 4*6 - 5 - 2*2 = 24 - 5 - 4 = 24 - 9 = 15
What is equivalent to 4 2-3?
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
How do you solve 5x-5 equals 3x-9?
5x - 5 = 3x - 9 add 5 to both sides: 5x =3x -4 subtract 3x from both sides: 2x = -4 Divide both sides by 2: x = -2
What is 3 x 4 x 5?
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
If 3x-5 equals 9 what is the value of x?
3x - 5 = 9 3x = 9 + 5 3x = 14 x = 14/3 or 4 2/3
What is the solution to the equations y equals 3x plus 4 and y equals 2 -7x showing key stages of work?
If: y = 3x+4 and y = 2-7x Then: 3x+4 = 2-7x So: 3x+7x = 2-4 => 10x = -2 => x = -1/5 By substitution: y = 17/5 Solution: x = -1/5 and y = 17/5
How do you solve for x when 4 to the power of 3x plus 5 equals 16?
(4^3x)+5=16 4^3x=11 now you can break it down by multiplying out the 3 64^x=11 then you take logs x= log(11)/6log2. Or if it's 4^(3x +5) = 16, then you can do it like this: 16 = 4^2, so we have: 4^(3x +5) = 4^2. The bases are the same, in the equation, so the exponents must be equal as well (you can take log-base4 of each side): 3x+5 = 2 --> x = -1
